Linux in a Nutshell, Fourth Edition

Name

yacc

Synopsis

                  yacc [options] file
               

Given a file containing context-free grammar, convert file into tables for subsequent parsing and send output to y.tab.c. This command name stands for yet another compiler-compiler. See also flex, bison, and lex & yacc (O’Reilly).

Options

-b prefix

Prepend prefix, instead of y, to the output file.

-d

Generate y.tab.h, producing #define statements that relate yacc’s token codes to the token names declared by the user.

-l

Exclude #line constructs from code produced in y.tab.c. (Use after debugging is complete.)

-o outfile

Write generated code to outfile instead of the default y.tab.c.

-p prefix

Change the symbol yacc uses for symbols it generates from the default yy to prefix.

-r

Produce separate files for code and tables named y.code.c and y.tab.c, respectively.

-t

Compile runtime debugging code.

-v

Generate y.output, a file containing diagnostics and notes about the parsing tables.
